Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553310, here are decompositions:

31 + 31553279 = 31553310
37 + 31553273 = 31553310
97 + 31553213 = 31553310
109 + 31553201 = 31553310
127 + 31553183 = 31553310
149 + 31553161 = 31553310
233 + 31553077 = 31553310
241 + 31553069 = 31553310

Showing the first eight; more decompositions exist.
